Suppose you have three resistor each of value `(30 Omega)`.List all the different resistances you can obtian using them.

Show how you would connect three resistors, each of resistance 6 Omega , so that the combination has a resistance of (i) 9 Omega , (ii) 4Omega .

Three resistors are connected in parallel with a 30V battery. A current of 7.5A flows through the circuit. If two out of the three resistors are of 10Omega and 12Omega , determine the resistance of the third resistor.

A short circuit occurs in a telephone cable having a resistance of 0.45 Omega m^(-1) . The circuit is tested with a Wheatstone bridge network have values of 100 Omega and 1110 Omega respectively. A balance condition is found when the variable resistor has a value of 400 Omega . Calculate the distance down the cable, where the short has occured.

When three resistors, each of resistance R, are connected in parallel, the equivalent resistance is found out to be 10 Omega . R must be …………………. .

You are given 10 resistors each of resistance 2 Omega . First they are connected to obtain possible minimum resistance. Then they are connected to obtain possible maximum resistance. The ratio of maximum and minimum resistance is .... .

The current flowing through each resistor is the same when resistors having different resistances are connected in parallel.

A set of n identical resistors, each of resistance R Omega , when connected in series have an effective resistance X Omega and when the resistors are connected in parallel, their effective resistance is Y Omega . Find the relation between R, X and Y.

Power transfer by a non-ideal cell to an external resistor can be same for two different values. Out of which on value (R_(1)) is less than internal resistance of cell and another (R_(2)) is greater than internal resistance of cell then:
